I have had this lovely green-throated historical daylily almost as long as I have been growing daylilies so it is another survivor for me
below is from 2002
Obtained from a Gulf Coast Daylily Society plant sale. Moved from the Gulf Coast with me after Hurricane Rita. Color is more intense in sunlight. Scapes have varied from 16-25" in the time I have kept records. Flower size has also varied from 3.25" up to 4". All seemingly depending on how much rainfall the plant gets before scaping. This cultivar is partial shade tolerant and will still bloom.
Focus is on the anthers in the photo below.
